Home Performance & Back drafting gas appliances - water heater recommendation?

I am working in the energy efficiency field. We see a lot of home performance contractors conducting home performance and home safety tests before and after weatherizing homes. One of the most common problems these energy efficiency contractors run into is the back drafting of gas water heaters and gas furnaces. It is often an issue that is more involved and we see a lot of them simply converting the home from a gas water heater to an electric water heater. Obviously, there are not any gases burned, so there cannot be any back drafting of exhaust.

While I like Marathon water heaters for their durability and performance - what types of water heaters would you recommend to home performance contractors or home owners running into back drafting gas appliances?

Would you default to a gas water heater with sealed combustion chamber? Tankless? Or a heat pump water heater?

It seems like the local folks can be overwhelmed by the options.

Backdrafting is an installation problem and can be overcome with the proper supply of air for combustion. Tankless is generally not a good choice for the average homeowner and would have the same issues anyway.
